COMBINED DOOR-CATCH AND DOOR-OPENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 363,666, dated May 24,1887.

Application filed March 26, 1886. Serial No. 196,737.

To aZZ whom it may concern.-

Be it known that I, CHARLES H. MILLER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania,

have invented certain new and useful Improvements in Combined Door Catchand Door- Opening Devices; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

r 5 My invention relates to improvements in combined door-catch anddoor-opening .devices; and it consists inthe improvements hereinafterset forth and explained.

My invention is illustrated in the accon1- 2o panying drawings, inwhich- Figure 1 is a perspective View of a section of a stove andstovedoor with my improved catch and door-opening device thereon. Fig. 2is a vertical end section of the same on the line 3 y in Fig. 1, lookingin the direction of the arrow y. Fig. 3 is a vertical end section of thesame on the line a: w in Fig. 1, looking in the direction of the arrowas.

Like letters refer to like parts in all the figures.

In the drawings, A is a section of the side of a stove, and B anordinarystove-door, having a latch, O, thereon of ordinary and usualconstruction. Directly under the point where the latch Omeets the frameI cast upon the frame A, or otherwise secure thereto, a lug, D,whichprojects outwardly from the frame A, so that the latch G will pass overit, the end of this lug D being provided with a notch, 11, for thepurpose hereinafter explained. To this lug D I hinge a lever, E, bymeans of a pintle, e, the

end of this lever E extending into a recess, F,

in the frame A, where it curves upward at f behind the latch 0, when thedoor B is closed (-5 against the face of the frame A. To the lever E, Ihinge a dog or catch, G, by means of a pintle, 9, this dog or catch Gbeing hinged to the lever E at a point beyond the end of the lug D onthe frame A. On the inner edge of the dog or catch G, I make a tooth orcog,

which operates in the notch d, hereinbefore' referred to, in the end ofthe l'ug D. The upreleasing thelatch 0,) and turning it out of the (Nomodel.)

per side, 9 of the dog or catch G is made of such shape that when thedoor is closed it rests upon or extends over the top of the lug D untilthe end 9 reaches the outside of the latch O, as illustrated in Figs. 1and 2, retaining the latch Oagainst the face of the frame A. When,however, it is desired to open the door B, the outer end, H, of thelever E is pressed downward, as illustrated in Fig. 3, which raises thepoint of the dog G, and at the same time turning it backward by theoperation of the cog g in the notch d in the lug D, (thereby 5 way, sothat the latch G will pass freely over the end 9 of the dog or catch G,the curved end f on the lever E operating simultaneously therewith toforce the latch O outward, therebyunlatching and forcing the door openat one operation.

In Fig. 3 Ihave illustrated in dotted lines different positions of theparts of the mechanism of my improved door-catch and door-opener, thedotted line E showing the position of the mechanism when the door isclosed and se cured, the full lines E showing the same as it appearswhen the door is fully released, and the dotted lines E showing thelever pressed down as it is in the operation of throwing the door open.

It will be observed that mydevice operates to latch and unlatch, and atthe same time open the door without in anywise lifting the doorB, it atall times swinging freely on its hingesI I, with its entire weightresting thereon.

I have thus shown a convenient form of mechanism for utilizing myinvention; but the same may be varied both in form and arrange ment ofpartsfor example, it might beplaced at the under edge of the door andoperate in contact with the lower edge thereof, instead of with a latchon the side of the door, as shown in the drawings, and good resultsobtained without departing from-the spirit of my invention.' Therefore Ido not desire to limit myself to the exact form of mechanism shown.

Having thus fully described my invention, so as to enable others skilledin the art to which it appertains to construct and use the same, what Iclaim as new, and desire to secure by Letters Patent of the UnitedStates, is-

1. The combination, in adoor-catch and dooropening device, of adoor-frame having a projecting lug thereon, a lever pivoted to said lug,

and a dog pivoted to said lever, with a door having thereon a catchclosing over thelug on the doonframe, substantially as and for thepurpose set forth.

2. In a door-catch and door-opening device, the combination of adoor-frame having a projecting lug thereon, and a recess at one side ofsaid lug, a lever pivoted to said lug, and a dog pivoted to said lever,with a door provided with a catch closing over the lug on thedoorframe,substantially as and for the purpose set forth.

3. The combination, in a door-catch and dooropening device, of adoor-frame provided With a projecting lug having a notch in the endthereof, a recess at one side of said lug, a lever pivoted to oneside ofsaidlug, oneend of which lever extends into said recess and the otheroutwardly beyond said lug, and a dog pivoted to said lever, having aprojection thereon operating in the notch in the said lug, with a doorhinged to said door-frame provided with a catch closing over said lug onthe door-frame, substantially as and for the purpose set forth.

4. The combination,with a stovedoor frame,

A,having recesses F therein, and the lug D,pro-

to the lever E, and having the cog g, intermeshing with the notch d inthe end of the lug D, all constructed and operating substantially as andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
